MANUAL RESET HI-LIMIT INSTRUCTIONS

FOR PHASE 6 MODELS

This dryer was manufactured with a manual reset burner hi-limit thermostat which is monitored by the Phase 6 computer. If the manual reset burner hi-limit thermostat is open prior to the start of the machine, the dryer will start momentarily and the shut down displaying “burner safety fail” with an audio indication.

If the manual reset burner hi-limit opens during a drying cycle, the display will read “burner safety fail” with an audio indication. If the drum temperature is above 100º F (38º C), the dryer will continue to run with no heat for three minutes or until the drum temperature has fallen below 100º F (38º C). The clear and stop button on the Phase 6 keypad must be pressed to clear this “burner safety fail” condition. The manual reset burner hi-limit switch must be reset “manually” prior to the start of the next drying cycle.

This hi-temperature condition may be caused due to a restricted exhaust, poor airflow or improper burner oven operation.

The location of the manual reset hi-limit switch is on the right side of the burner box.
